3-Buten-2-one, 4,4-dichloro-, (2,4-dinitrophenyl)hydrazone is a chemical compound with the molecular formula C10H8Cl2N4O4. It is a derivative of 3-buten-2-one, also known as methyl vinyl ketone, which is a colorless liquid with a pungent odor. The compound is characterized by the presence of two chlorine atoms at the 4-position and a 2,4-dinitrophenylhydrazone group attached to the carbonyl group. This hydrazone derivative is often used in organic chemistry for the detection and identification of carbonyl compounds due to its distinct color and crystalline properties. The compound is synthesized by reacting 4,4-dichloro-3-buten-2-one with 2,4-dinitrophenylhydrazine, resulting in a product that can be used in various analytical applications, such as thin-layer chromatography and spectrophotometry, to detect the presence of carbonyl groups in complex mixtures.
The CAS Registry Mumber 5780-62-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,8 and 0 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5780-62: (6*5)+(5*7)+(4*8)+(3*0)+(2*6)+(1*2)=111 111 % 10 = 1 So 5780-62-1 is a valid CAS Registry Number.
